they pass through channels in the cell membrane.
Which of these molecules is polar
fats, oils, lipids are all hydrophobic.
large or polar molecules such as proteins, glucose or ions like Na+/K+
Hold polar molecules together
false. they are non polar molecules, not to be confused with polar molecules. non polar molecules lack regions of electrical charge. it mostly has hydrogen and carbon atoms. an example of non polar molecules are fats and waxes.
they pass through channels in the cell membrane
Non-polar molecules are more attracted to other non-polar molecules.
Which of these molecules is polar
Polar molecules have charges that non-polar molecules do not have. It is the reason why non-polar molecules can move through the lipid bilayer quicker than the polar molecules.
Water is polar while oils are non-polar. Molecules that are polar will mix with other polar molecules, and non-polar molecules will mix with other non-polar molecules. Polar and non-polar molecules will not mix.
fats, oils, lipids are all hydrophobic.
large or polar molecules such as proteins, glucose or ions like Na+/K+
Because small non polar molecules are the ones able to cross due to the fact that the membrane consists of a phospholipid bilayer where the middle is composed on non polar tails
Hold polar molecules together
Polar molecules dissolve in water. The reason why polar molecules dissolve in water, but not non-polar molecules is because non-polar molecules can't form hydrogen bonds.
Polar molecules are mixed better with water.
Water molecules are polar molecules. Both of the bonds inside the molecule are polar bonds.
